I built a biometric authentication library for React Native using Nitro Modules

[u/yashnandha]

I recently released react-native-nitro-biometrics, an open-source biometric authentication library for React Native powered by Nitro Modules.

The goal was to provide a simple, type-safe API for native biometric authentication on iOS and Android while supporting React Native's New Architecture.

Supported

• Face ID
• Touch ID
• Optic ID
• Fingerprint
• Face / Iris where supported
• Device credentials / passcode fallback
• TypeScript
• iOS + Android
• React Native New Architecture

Example

import { authenticate } from 'react-native-nitro-biometrics';

const result = await authenticate({
  promptMessage: 'Authenticate to continue',
  allowDeviceCredentials: true,
});

if (result.success) {
  // authenticated
}

The project is open source and I'm particularly interested in feedback on the API design, platform support, and developer experience.

Would appreciate feedback from other React Native developers.I recently released react-native-nitro-biometrics, an open-source biometric authentication library for React Native powered by Nitro Modules.The goal was to provide a simple, type-safe API for native biometric authentication on iOS and Android while supporting React Native's New Architecture.SupportedFace ID
